Application filed March 24, 1902. serial No. 99,823. (ll!) model.)

' citizen of the United States, residing at Ohisary adjustments.

cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Surgical Chairs; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon,- which form a part of this specification.

The object of this invention is to form a folding surgical chair particularly useful in administering rectal or vaginal douches or injections.

A further object is to form a folding chair of the class stated which will occupy comparatively little space when folded and which may be adjusted when in use to give any or dinary degree of pelvic elevation.

An embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the chair with the back lowered. Fig. 2 is a side elevation with the back raised. Fig. 3 is a side view of the chair when folded. Fig. l is a top View of the chair-seat, and Fig. 5 is avertical section thereof.

Referring specifically to the drawings, 6 indicates the spreading legs of the chair, which are pivoted together at the top, as at 6. The chair-seat 7 swings on the same pivot 6 and has a le -rest or extension 7, hinged at 7' to the front edge thereof. A spring-catch 7, carried by the extension, engages the seat to hold the leg-rest straight therewith when desired. The back is indicated at 8 and is hinged to the seat by a bolt 9, which is threaded to receive a hand clamping-nut 9. The side frames of the back are slotted, as at 9 to receive the bolt and to permit the neces- By means of the nut, bolt,

and slot the back may be inclined at various degrees to the seat and clamped at such adjustment. The lower ends of the side frames of the back stop against the blocks 10, at-

conveniently made to discharge into a pail.

13. The seat and its cushion are made to incline from all sides to the opening 12 to direct the liquid thereto, and the liquid will not ,run down the back even though the back be lower than the seat.

6 indicates folding braces connecting the legs.

\Vhat I claim as new is- 1. Achair eomprisinglegs pivoted together at the top, a tilting seat pivoted at the top of the legs and having admin-opening therein, and a back joined to the seat and having its lower end in adjustable supporting contact with the legs.

2. A surgical chair having a tilting seat and back, with a drain-opening in the seat, and a cushion on the seat behind the opening and inclined downwardly and forwardly thereto.

3. In a surgical chair, a tilting seat having an opening, and acushion on the seat ridged around behind the opening to direct liquid thereto, the cushion-cover extending through the opening to form a'discharge-spout.

4. A chair comprising legs, a rocking seat pivoted thereon having a forward extension hinged thereto, and a back hinged to the seat behind its pivots and having a projecting portion in supporting contact with the legs.
